What causes resistance in a conductor? - Answer-The
Type: Copper/ACSR,
Size, Length, and Temperature (the more heat more
resistance.)
How do you take a capacitor off line? - Answer-Open oil
switch or open cutout with load break. The internal resistor
should bleed the voltage to 50 volts or less in 5 min. Then
shunt and ground the capacitors.
What do capacitors do? - Answer-Improve power factor,
when the current is lagging the voltage.
Why does a recloser stay energized longer on the 3rd or
4th shot? - Answer-To allow a fuse to blow if there is a tree
fault and also to narrow down the area of the fault after the
fuse blows.

The reason it holds open is to allow an sectionalizer to
open cause it operates under no voltage.
What determines the strength of a magnetic field? -
Answer-the current
Types of over current protection? - Answer-Circuit breaker,
Recloser-OCR, and Cutout.
Can you look at a circuit breaker and determine the line
voltage? - Answer-NO (Because they are not rated in
voltage just amps)
In CPR how many chest compressions are needed to how
many breaths? - Answer-30 Chest compressions to 2
Breaths 30-2
How would you parallel two regulators? - Answer-Leave
them on the step they were at, lock them down, and turn
them off. Once the work is complete put back to manual.
OR take one or both off line and do the same thing.
LTC is powered by? - Answer-PT by volts

Safe working limits with ropes? - Answer-If the breaking
strength of a rope is 5,000lbs and the assigned WLL is
1,000lbs then the safety factor is 5.
Color of service lines on vehicles? - Answer-Red-
Emergency
Blue- Service
Green- Electrical
Delta Secondary Voltages? - Answer-Delta doubles
(Phase to phase is always 2 x Phase to neutral.)
WYE Secondary Voltages? - Answer-Phase to phase is
always 1.73 x phase to neutral
Shoring and Latter placement? - Answer-3 4 5-Shoring
Latter extends 3' past rest point
At 4' you need a ladder
At 5' you need shoring
1 Ladders every 25'
